A Brazilian neuroscientist says brain-controlled robotics will let the paralyzed walk again. By Antonio Regalado

Words, I swear to god the trouble they've caused. I awake every morning with questions that torment me. The who, why, how, when of everything unanswered. They taught me to read and write but were more interested in content and context, what I read or didn't read. They taught me to recognize what the marks on paper meant, actually it was an initiation into the foolishness of words. Starting with children's books I learned to open my mind to the foolishness to come. I didn't know words could lie so unashamedly. Behind the mask of ego and motive, like a magicians slight of hand, the amusing joke, I'm doubled-over in laughter while going to my slaughter. Words can kill, damn, I thought words were innocent, some fool said "if".

Words are coined for schools of thought. The more immersed in the school the more serious the words. For a truth, I tell you this surely must be the truth because I so thoroughly believe it to be true. Others from the first written to the contemporary have verified it to be so and all other words are incarnations of evil set to confuse or destroy the believers of the truth. Why isn't the truth itself is destroyed, why the believers of the truth are destroyed? It is because words for and against must occupy the same space. We don't care about the question in question, we care about the words. Oh, how we revere words.

Words are a formula expressed to convey and communicate to others but in the fact that a person can communicate one thing and think another, words are highly suspect. The alien with a big zipper on his forehead, unzipped to reveal a big honking eye, his jaw automatically locked, the full spectrum of his data stream into my mind and I knew his intent, motive and reason, not a word was spoken. I felt like god had descended and swept away years of nonsense, the years of interpretive equations for every occasion and defensive quips to hide my fears. Oh the elation of pure knowledge that stopped all the human foolishness that has enveloped me. I am sure I must tell others.

Words, just words, like other words. My cousin James was abducted by aliens, he said. Oh, they had something about that on TV the other night. What you been smok'n mon? I am a _______________ and we don't believe in that, if you read the _____________you'd know god's word. God's got a mouth now, has lips, speaks words. His words, even if you repeat them are powerful words.

The mind is powerful in how it perceives and believes, conceives and receives, can also deceive and be deceived. Words themselves are the power. They strike the mind through the eye ports, the ear port, the mouth port. Thus we are mostly blind, deaf and dumb by reason of all the words we are bombarded with and the constructs of their definitions we exist in.

He's well read, is a man of letters, has a way with words, is a word mister, a word smith, is a walking lexicon and a con-artist. He is who said it first, coined the word, defined the word and redefined the expression. It's all about the words. Words are the real weapon. Like in Star Wars and every street fight, you play the dozens, can't settle it, then break out the fisticuffs or light sabers or guns. I see we can't settle this with our knowledge of the force (words), have to use the elegant weapons of a more civil time, bashing with stones, swords, throwing bullets, arrows, rockets, packets of erroneous data and viruses, sanctions, all the other things we do to each other because our words have less power that another's words. And it is because our words do not match our reasons and motives. The same is true for both sides. How in the heck can we move forward if our words were true? Both sides ask the same question. On this planet, words are the problem.

A picture speaks a thousand words. We should all be artist. There would be less need to speak. Oh, I forgot, we don't see eye to eye either.

Gravitational Waves Mystery May Be Solved Using Powerful Lasers

The ripples from violent cosmic collisions can be felt far across the universe, and thanks to a new, sensitive detector expected to start collecting data next year, scientists might be able to see evidence of those gravitational waves from Earth for the first time.

When two neutron stars (remnants of supernova explosions) merge or when a black hole merges with a neutron star, the reverberations of the merger can extend throughout the cosmos. Light, however, only tells us so much. To learn more about the mass and motion of the collision, astronomers want to use gravitational waves, ripples in space-time created during these massive crashes.

Next year, astrophysicists are set to switch on one of the most sensitive gravitational-wave detectors ever created. The observatory is called the Laser Interferometer Gravitational-Wave Observatory (LIGO, for short). It originally had six observing runs between 2004 and 2010, and has been offline for half a decade to make upgrades. The return, its backers say, will be worth it. [Photos: Hunting Gravitational Waves with LIGO]

"It opens us up to [viewing] a larger number of astrophysical events," said David Reitze, the LIGO Laboratory's principal investigator and director. One improvement will be better sensitivity in lower frequencies, which will let astronomers look for black holes of between 100 and 500 times the mass of the sun if they exist.

A new documentary about LIGO, titled "LIGO, A Passion for Understanding," is set to premiere on Space.com April 15. You can watch it on Space.com or directly from the filmmaker Kai Staats here: http://www.kaistaats.com/film/ligo/.

From the Big Bang to big star explosions

Gravitational waves hit the headlines in March when the scientific instrument BICEP2 (short for Background Imaging of Cosmic Extragalactic Polarization) found the first direct evidence of cosmic inflation, or the huge expansion of the cosmos that happened shortly after the Big Bang.

LIGO, however, searches for waves at higher frequencies, in the 10 hertz to 10 kilohertz band. The primordial waves discovered by BICEP2, Reitze said, are 20 orders of magnitude lower in frequency.

While LIGO was not really designed to look for primordial waves, scientists did search for them. Researchers described what was then the most accurate upper limit on the primary gravitational- wave background in high frequencies. The results were published in a 2009 issue of the journal Nature in 2009 (and have since been superseded by BICEP2, Reitze said.)

Another prominent result came when scientists measured how round pulsars — super-dense, tiny, spinning remnants of supernovas — are by tracking asymmetries on their surfaces. "If it has a bump and the bump is big enough, it will generate a gravitational wave," Reitze said.

Measurements of the Crab Nebula's pulsar by LIGO yielded no "mountains" higher than one meter (3.4 feet). "Certain pulsars, are even better, with less than a millimeter high," Reitze added.

Stopping for trains and earthquakes

LIGO originally consisted of two interferometers (telescope receivers that work together) at Hanford (near Richland, Wash.) and one in Livingston, La. The $205 million advanced LIGO has one interferometer in each location, with the third one going somewhere off continent — likely India. The government there is calling this project "one of the hallmark science detectors," Reitze said, and site evaluation is underway.

Wherever the interferometer goes, it has to be a region that is not too prone to earthquakes, lest the sensor get mixed up. Despite advanced stabilization technology, shaking does happen. "And we monitor the shaking to make sure it doesn't corrupt the data," Reitze said. [Watch the trailer for "LIGO, A Passion for Understanding"]

There's a procedure at Hanford and Livingston to stop science work when earthquakes occur. Observations at Livingston also must stop temporarily if a 50-car cargo train rumbles by on a track about 1.5 miles (2.4 kilometers) away.

"There are automatic protocols (using sensors and software) which monitor earthquakes and take the interferometers out of 'science mode' during seismic disturbances from earthquakes," Reitze said.

Each interferometer works by injecting a laser into a vacuum system, which splits the beam in half to put the resulting beams at right angles to each other. Each beam goes to mirrors about 2.5 miles (4 kilometers) away, which reflect back.

The gravitational waves cause tiny but measurable distortions in the laser beams that cause a "changing interference pattern" in the photosensors that read the laser reflections, Reitze said. "In comparative scale, if you take the nucleus of an atom and take its diameter and divide that by 10,000, that's the type of a distance change we're looking at."

LIGO's capabilities will be 10 times more sensitive than before in searching for binary neutron star mergers, and it will be better able to pick up on many other cosmic phenomena as well – such as black holes and supernovas. The principal funder was the National Science Foundation, and the California Institute of Technology leads laboratory operations.

Universal Greetings to everyone on this site:

I watched the brother's rant just now, and my first issue is "Why does it sound like he is stuck on discussing what Hollywood isn't doing and on certain Black characters from the mainstream comics industry?" This topic goes around in circles every day, month, year, whatever. I've been on different sites and I see and read about this same issue. I've made it plain when I respond to these posts: I do not care what Hollywood is or is not doing with their Black characters! I mean c'mon, its been obvious since the beginning of the American film industry in this country that they do not nor have they ever cared about our culture.

We need to do for self as the great Marcus Garvey kept on emphazising during his time in the early 1900s, and we had our own small, yet creative "Black Hollywood" in those times (and I'm talking about more than the great Oscar Micheaux). We already have a large group of Black superheroes of African culture, science fiction, etc. that we can research and get together to collaborate on to produce them.  I don't care if it comes out on NetFlix streaming service, straight to DVD, Video on Demand (VOD), whatever format would be viable for folks to view it. You want the best deliverable format with the lowest cost of distribution so that you are not overextending your overall budget.  Go to the (small, yet entertaining) various Black comic conventions in this country and meet the creators, talk about their characters, and other future projects or ideas with them.

I am tired of reading posts about only Luke Cage, Black Panther, Storm, etc. My second issue is why do we have to dream cast the same person (s) for a role (I.e. Michael Jai White as either the Black Panther or Luke Cage)? He is not the only male Black actor out there, people! What about Morris Chestnut or Henry Simmons? We have more than Zoe Saldana to act as a comic book-based character, right? It seems to me that television gives more interesting role choices than film is doing. ECBACC, Black Age in Chicago, Motor City in Detroit, etc. are great places to discover our characters and creators. I have a friend and creative partner based in Los Angeles, and for example, he would love to do a massive possibly animated film featuring if not all but those who are willing to contribute based on using the Black Superhero Montage characters. Now wouldn't that be something spectacular? Now maybe folks who are stuck on Hollywood would shut the hell up finally?

It takes a lot of people, a whole lot of money, a definite whole lot of commitment to do for self. Lets stop complaining, stop bringing up racism as a blockade, stop dream casting, lets get off our collective asses and go learn whatever skills we need to have to make these projects become reality. To be continued...

A little under a year ago, I started a side projected called Bad Girl Confidence to showcase a collection of aspiring creatives that I knew. Creatives such as writers, designers, comic book writers, artist, musicians, & entrepreneurs who needed exposure for their work but lacked the resources to drum up support for their work. Find out more here: www.badgirlconfidence.com

This platform is now growing into an online magazine and we will going into print as a result. We will be bringing the website and print magazine at the Northside Festival in June. The print magazine is going to include a variety of artist, all but one are people of color from around the world. There are illustrators, video game designers, graphic artists, fine art creators, and more. If you would like to help us make this magazine a reality, please pledge here: http://igg.me/at/bgcmagazine

Your pledge could earn you a copy of digital and/or print magazine. I am really excited because this is the first step in showing the world the emerging talents coming out from our communities. My main focus is on people of color but I engaged in the spirit of encourage talent full stop! This magazine is here to bring a different perspective and balance the skewed media conversation about what beauty and talent looks like!

Thank you for your help! :)

I will be revealing the new cover for The Beggar's Bowl on May 21. This short of mine has been free for a few years now and I know it hasn't gotten as many downloads as 30 Minute Plan because the cover is just awful. I'd made it myself. But now it has an honest-to-goodness nice cover and I will be revealing it next month in anticipation of the release of Axe to the Face. TBB will also include an exclusive excerpt of the novella.

Don't forget to download a copy of Where the Monsters Are or join the giveaway over at Brutal Books!

I listened to this podcast a few times and found it very cool to hear. This is where coders, tech experts, and entreprenuers, authors, engineers, etc get on and talk about their experience in the field.

Widespread Bug Will Linger On in Unpatched Devices
Money.CNN.com: Heartbleed bug: What you need to know
LA Times: 'Heartbleed' bug could undermine years of work to build public trust

In college I was introduced to the utopian novel, heard much of hippie communes and investigated several religions and such, ultimately getting stuck in one. The weird thing is that for every serious group, there is a vocabulary. That group of words dictates the context of the reality of that group. Outsiders are separated by not knowing the language and/or not participating in the fellowship using that language. What I mean is you have experiences (mostly normal human experiences) and you describe them in the language of the group. The end effect is that you must use the appropriate language with the appropriate group. Mixing groups and languages is for dissing or promoting the one group to the other group.

Now if you spend any length of time in a focus, using a particular language and describe your world through the defines taught to you, you will find your being has been altered accordingly. Take my word for it, when a startling change comes, it is a struggle to deal with it internally.

The one who knows this experience is the traveller. If you've been to another nation where the culture and language is foreign then you have the alien experience. Now let's shift gears and change realities. Now you know very little experientially. You hope if you go through this door you can come back through. Then can you describe what you experience to yourself because you sure as shoot'n will have a hard time describing it to others.

I haven't been there yet, but I sense it in the back ground, where the times and names mean nothing. I wonder if my sense organs and brain are giving me all that is or a narrow spectrum. I heard one say if I rub my hands together, I am ramping up my chi. I don't want to waste energy, I do want to see energy fly from my hands, not just assume. Power of life, what a thought and yet I've been taught not to consider it or develop it. Power of mind, beyond the meanings in words I've been taught, beyond the reality I learned to sense. OR is what is exactly what it is? Perhaps it is imagination after all.
